HAY-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 635,110, dated October 1*?, 1899.

Application filed May B, 1899. vSerial No. 715,967. (No model.)

To @ZZ whom it may concern.'

Be it known that l, JUDsoN D. SwAc1cK,a citizen of the United States, residing at Canton, in the countyof Stark and State of Oh'io, have invented certain new and useful Im proveniente in Hay-Elevators; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the :figures of reference marked thereon, in which- Figure 1 is a side elevation showing the carriage released from the stopblock and the elevating-head partially hoisted. Fig. 2 isa detached view of the rope-clamping and its different parts. Fig. 3 is a view showing a portion of the carriage-frame, also the triplever and one member of the bumper.V Fig. 4. is a sectional view of the carriage-frame, showing the carriage released from the stopblock. Fig. 5 is a vertical section through line at or, Fig. 1, when vcarriage is locked to formed integral with the frame 2 and the circle or band 5 being cast or formed integral track.

The present invention has relation to hayelevators; and it consists in the different parts and combination of parts hereinafter described, and particularly pointed out in the claims.

Similar nul'nerals of reference indicate cor-` responding parts in all the iigures of the drawings.

In the accompanying drawings, 1 represents the track or way, which is supported The carriage-frame 2 ma 7be substantiall l s 5 .Y

of the form shown, and to which carriageframe is connected the swivel-frame 3, said frames 2 and 3 being connected together by the tongue-and-groove circular bars or bands 4c and 5, the circular band fl being cast or with the swivel-frame 3. p

For the purpose of providing a means for' properly connecting the two frames together' the frame 2 is preferably formed in sections `of the clamping-bolts G.

or .members and the members clamped together at their bottom or lower ends by means To the carriage or frame 2 are pivotally connected the bars 7, to Which bars are journaled the traveling wheels 8, one traveling wheel being located at each end of the pivoted bars 7. The object ,and purpose otA arranging the traveling Wheels 8 as shown and described is to better distribute the weight upon the track or way.

To the track or way 1 is securely attached `the block or `head 9, said block or head being connected and held in a fixed position by means of the clamping-bolts 10. At a point below the block 9 is located the plate ll,which plate is provided with the bumper or stopblock l2, said bumper extending a short dis tance downward and is for the purpose hereinafter described, the plate 11 and its bumper being securely held in proper positionby means of the clamping-bolts 10. The head 9 lis provided with the arm 13, to which arm is `pivotally connected the triplever 14, to which trip-lever 14E is pivotally connected the detent 15, said de-tent being held and guided by or held in a fixed position upon the track or way 1.

The frame 2 is provided with the sliding.

bars 19, which sliding bars are located in ways formed -upon the sides of the frame2 and are held in proper relative position by means of the caps or plates 20, and for the purpose of limiting the downward movement of the sliding bars 19 they are provided with the pins 21, which pins strike the top or upper ends of the cap 20.

To the swivel-frame 3 are connected the bumper-bars 22, which bumper-bars extend vdownward through guides formed in the sides of the swivel-frame 3 and are provided with the strikeplates 23. For the purpose of holding the bottom or lower end of the bumper- ICO bars 22 in proper relative position the clamping-bolt 24 is provided, which clamping-bolt connects the bottom or lower end of said bumper-bars together. The bumper-bars 22 are each provided with the pins 25, which pins are for the purpose of limiting the downward movement of the bumper-bars, said pins striking the bottom ends ofthe slots 26,which slots are formed in the swivel-frame 3, as illustrated in Fig. 5.

To the swivel-frame 3 is pivotally attached -.the dog 27, which dog is substantially of the formshown and is so arranged that when the carriage comes under the block 9 and the stop-block 12 its top or upper end will strike the stop-block 12 and the top or upper end of the dog 27, which in turn forces the inner upper end of the elevating-rope-connecting lever 28 downward and its outer end upward, by which arrangement the lower portion of the lever 2S is'moved away from the elevating-rope 29, which in turn releases the clamping-block 30 by means of the connecting-bars 31 said connecting-bars being pivotally attached to the clamping-block 30 and to the bottom or lower end of thel lever 28. When the dog 27 has reached the point so as to be tripped by the stop-block 12, the traveling carriage proper is in such a position that the detent 15 will drop, thereby causing the flanges 18 to engage the notches 17, and thereby lock the carriage in a fixed position upon the track.

It will be understood that when the lever 28 is elevated at its outer end the elevatingrope 29 will be free to move over the pulley 32, and when elevating-head 33, together with its load, has been hoisted until the top or upper end of said elevating-head strikes the bumper-plates 23 and elevates the bars 22 the top or upper ends of said bars 22 willstrike the bottom or lower ends of the sliding bars 19 and elevate the same, by which arrangement the detent 15 will be lifted, so as to release the flanges 18 from the recess 17, at which time the carriage, together with its load, is free to move upon the track or way.

When the carriage has moved away from the stop-block 12, the dog 27 is released, and by reason ofy the downward pull of the elevating-rope 29 upon the outer end of the lever 2S the bottom or lower portion of said lever will be thrown or forced toward that portion of the elevating-rope 29 j ust below the pulley 32, and thereby clamp the elevatingrope between the clamping-block 30 and the inner face of the rope guide or thimble 34, said rope guide or thimble being formed integral with the swivel-frame 3.

The clamping-block 30 is located upon the vinclined plate or part 35, said part being located at one side of the rope guide or thimble 34.

In use when it is desired to have the carriage moved along the track or way before the elevating-head 33, together with its load, has reached a point where said elevating-head 36, which trip-cord is extended upward andover the pulley 37, said pulley being located a short distance above the free end of the trip-lever 14. It will be understood that as the trip-lever 14 is elevated by the trip-cord 36 the detent 15, together with its flanges 18, will be lifted, so as to disengage said flanges from the notches 17, at which time the lever 28 will be p ulled downward at its outer end, and the clamping-block 30 forced against the elevating-rope, so as to lock said elevatingrope or load in the same manner that the load is located when the trip-lever is elevated by means of the bumper-bars 22.

The object and purpose of pivotally connecting the clamping-head 30 to the connecting-bars 31 is to allow said clamping-block to automaticallyadj ust itself, so that the clamping-block will press or bear equally upon the elevating-rope upon all points of contact.

It will be understood that the end of the clamping-block 30 designed to come in contact with the rope, should be concave, as

illustrated in Fig. 2.

By locking the elevating-rope at a point below the pulley 32 the leverage is removed, or, in other words, when the elevating-rope is locked forward of said pulley the downward pull over said pulley acts as a lever upon the rope,and thereby adds to the pulling strength.

By lookin g the block 30 on the inclined part 35 the downward pull of the elevating-rope has a tendency to wedge 'said locking-block against the elevating-rope, and thereby bind said r'ope against said locking-block and thimble or guide.

Having fully described myinvention, what I claim as new, and desire to secu re by Letters Patent, is-

1. The combination of a track or way,l a carriage consisting of frames swiveled together one located above the other and the upper frame provided with traveling wheels,
